Never touched a mask at the show except for going into the Carlisle store to buy the 2020 van diecast, wore one at Walmart and a bar I went to they required it when walking in the door but not afterwards. I feel the same as normal, but that doesn't necessarily tell me anything...
please define your version of normal??
Doctors can't even define that with me...
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
